Abstract： Urbanized areas are areas whose main function is to provide industrial and service products. During the 15th Five-Year Plan period, the urbanization rate of China’s population will exceed 70 percent, thus entering a long-time stage of high urbanization levels. The strategic positioning of urbanized areas will be defined as county-level administrative districts with a high concentration of scientific and technological innovation resources, new quality productivity, and new-type industrialization. In terms of strategic layout, the scope of urbanized areas will be optimized to promote the concentration of population and economy in urban agglomerations, metropolitan areas, and central cities, and to strengthen the suburbanization of mega cities, as well as the integrated development of urban and rural areas. In terms of functional upgrading, it will promote the layout of new quality productivity and new industrialization in different urbanized areas according to their comparative advantages, and strengthen the leading role of Beijing-Tianjin-Hebei, the Yangtze River Delta, the Pearl River Delta, and Chengdu-Chongqing area. In terms of spatial quality, it is necessary to promote the livability, intelligence, and resilience of cities.

Abstract： Realizing the Beautiful China Initiative is the general goal of China’s ecological civilization construction in the next 30 years. The overall goal includes two phased goals: “35 goals” and “50 vision”. This study first expounds the understanding of the goal from the aspects of ecosystem elements, structure, process, and function, and then constructs an index system to describe the goal and simulates the “35 goals” and “50 vision” under the trend of climate change, population decline and economic growth. The results show that, by 2035, China will have a population of 1.44 billion (including Hong Kong, Macao, and Taiwan) and a GDP of 200 trillion yuan, making it one of the moderately developed countries. The national forest coverage rate will be 26%; the quality of surface water will reach above Class III, and the quality of offshore waters will reach Class II or above; and urban air quality will reach national excellent standards. By 2050, the country will have a population of 1.365 billion and GDP 380 trillion yuan, entering the ranks of high-income countries. The national forest coverage rate will be 30%; the water quality of surface water and offshore waters will reach Class II standards; and the urban air quality will reach the level of developed countries. There is still a clear gap between the reality and the vision. To achieve the two phased goals of the Beautiful China Initiative as scheduled, we need to vigorously promote pollution reduction, carbon reduction, green expansion, grain increase, and green development in the future.

Abstract： Urban agglomerations, including Beijing-Tianjin-Hebei, the Yangtze River Delta and the Pearl River Delta regions, are the large clusters both from population and economic perspectives and have the most active vitality of innovation. To be the worldclass urban agglomerations, population function regulation should highlight the roles of the carrying capacity of resources and the environment, allocation of public service resources, and the challenges of global competitions in the fields of economy and technology. We firstly review the classic theories. Then the distinct characters of population development in China’s urban agglomerations are figured out. Accordingly, the basic laws of population function regulation in urban agglomerations are put forward. In addition, the differentiated strategies are introduced to optimize the population functions in Beijing-Tianjin-Hebei, the Yangtze River Delta and the Pearl River Delta regions. Our policy implications aim to promote evolution of urban agglomerations with a more advanced and healthier process, especially during the 14th Five-Year Plan period.
